Short-term toxicity to fish
Administrative data
Link to relevant study record(s)
Description of key information
In the short term toxicity test to fish the LC50 value of the test substance, 2-Propylheptyl methacrylate based on the loading rate was determined to be >0.055 mg/L.
In the short term toxicity test to fish the NOEC value of the test substance C17-Methacrylate based on nominal (loaded) concentration was >= 100 mg/L.
Key value for chemical safety assessment
Additional information
No data are available for 2-Propenoic acid, 2-methyl-, C13-C15-branched and linear alkyl esters, but for the read-across substances 2-Propylheptyl methacrylate (CAS 149855-64-1) and C17-Methacrylate (CAS 1473386-29-6).
The short term toxicity test to fish was conducted according to the OECD guideline 203. The acute lethal toxicity of 2-Propenoic acid, C16-18-alkyl esters to Danio rerio (Zebrafish) under semi-static exposure conditions over a period of 96 h. The singly applied loading rate was 100 mg/L. No mortality or toxic effects were observed. Based on this result the LC50 value of 2-Propylheptyl methacrylate is considered to be >0.055mg/L (mean initial measured concentration).
In a 96 hour acute toxicity study, zebrafish (Danio rerio) were exposed to C 17 Methacrylate at nominal (loading) concentrations of 0 (control), 100 mg/L under static-renewal conditions in accordance with the OECD 203 test guideline. The water pH, temperature and dissolved oxygen were within acceptable guideline specifications. The 96 hour NOEC was ≥100 mg/L based on the nominal (loading) concentration of the test substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
